Reviews

I still need to do more testing but this is awesome!
I was planning to build my own custom taxonomy reports but I guess this plugin might do exactly what I need and do the heavy lifting for me.
The only trick is to make sure the custom taxonomies are created after woocommerce_register_taxonomy and not the usual init. After everything works perfectly!
